Dwyer 285ER-D5 | Rotary Smart Positioner | HART, double acting, aluminium
Dwyer 285ER-D5 is a Series 285 rotary smart positioner configured double acting, with HART communication and an aluminium enclosure. Using a 4-20 mA controller signal, it sets the travel of rotary valves such as ball and butterfly valves, and an external LCD shows status in the field.
- 285ER-D5 auto calibration and analog feedback output
- 285ER-D5 enclosure rated NEMA 4X (IP66)
- 285ER-D5 rotary stroke 0 to 90°; fails in place on loss of 4-20 mA signal
- Air supply for the 285ER-D5: 20-101 psig (1.4-7.0 bar)
- 285ER-D5 connections: 1/4" NPT air, 1/8" NPT gauge, 1/2" NPT, screw-terminal electrical
